Description

I notice a few ports for the ESP32 family, including a couple of lower-spec Lolin boards, plus generic ESP32-S3 ports. But these don't accommodate boards like the Lolin ESP32-S3 Pro with its 16MB Flash and 8MB PSRAM.

Is there any possibility of ports in the near future, for this board, and other newer/higher models of ESP32?

Assessment

S Sonnet · medium

The query requests a port for the "Lolin ESP32-S3 Pro" with 16MB Flash and 8MB PSRAM. The candidate PR adds a LOLIN_S3 board definition with identical key specs: 16MB Flash (Quad SPI) and 8MB PSRAM (Octal SPI). These are technically distinct Wemos products — the LOLIN S3 and LOLIN S3 Pro — so the PR does not exactly target the board named in the issue. However, if the PR is merged, the LOLIN S3 board definition may already satisfy the requester's actual hardware (same silicon, same memory configuration), and the issue author may simply have used the wrong product name. Confidence is medium rather than high because the Pro variant may have different peripherals or pinout.

Suggested action

Check whether PR #9177 has been merged. If merged, close issue #17217 as likely resolved — the LOLIN_S3 board definition covers the same ESP32-S3 with 16MB Flash + 8MB PSRAM. Add a comment noting the distinction between LOLIN S3 and LOLIN S3 Pro, and ask the reporter to confirm whether the merged board definition works for their hardware before closing.
